TWO-ROW ANTIFRICTION BALL BEARING Russian patent published in 2017 - IPC F16C19/18 F16C33/58 

FIELD: machine engineering.

SUBSTANCE: two-row antifriction ball bearing has an outer (1) and internal (2) rings, separators (3, 6) to separate the rolling elements. The rolling elements are made in the form of balls (4). Each ring (1, 2) is made with two raceways and flanges along the raceways edges, the larger flanges are located as follows: one flange (6, 9) on one outer end of the ring, the other flange (5, 8) between the raceways on the axis of bearing symmetry, and a smaller flange (2, 7) with a bevel at the other outer end of each ring (1, 2).

EFFECT: increased maximum permissible load, perceived by the bearing as a whole, and its operation longevity.
